What should you know about umbilical cellulitis?

The skin around the navel may become red, warm, tender, swollen, or tight. Some people notice cloudy fluid, pus, an unpleasant smell, or a crust in the navel. Fever or feeling generally unwell can accompany the infection, but their absence does not rule it out.

A small break in the skin, trapped moisture, piercing, wound, or another local problem can allow bacteria to enter. Conditions that affect immune response or healing, including diabetes, can make skin infections harder to manage. A clinician may inspect the area and decide whether prescription treatment, drainage, or further testing is needed.

Arrange same-day medical advice for new or spreading redness, increasing pain, swelling, pus, or a tender lump near the navel. Keep the area gently clean and dry, wash your hands before touching it, and use a clean dressing if fluid is rubbing against clothing.

Do not squeeze the area, insert cotton buds, apply leftover antibiotics, or cover it with an airtight dressing. Take prescribed medicine exactly as directed and complete the course unless the prescriber changes it. Marking the edge of redness can help show whether it is spreading while you await advice.

Seek urgent care for fever with rapidly spreading redness, severe pain, red streaks, confusion, faintness, fast breathing, repeated vomiting, or unusual sleepiness. These can signal a serious infection requiring immediate treatment. Infants, older adults, and people with diabetes or reduced immunity should be assessed promptly for any worsening navel infection.

Could this be cellulitis, an abscess, or another navel problem? Does the area need a swab, drainage, or prescription medicine? What changes should make me return urgently, and how should I clean and protect the skin while it heals?
